That said, one of the merits of Friedman's “dynamic geography” is that it is not really a “libertarian” project at all. As he writes in his Unbound lead essay:

Because we have no a priori knowledge of the best form of government, the search for good societies requires experimentation as well as theory — trying many new institutions to see how they work in practice.

I think there's good reason to expect competing sea-top jurisdictions to settle on a scheme of governance more libertarian than what the world's current nation states have to offer. But I also think there's little reason to expect a seastead to embody the system of most libertarians' dreams unless a lot of libertarians coordinate and settle there. In that case, it's really clear that creating a libertarian society from whole cloth depends on the prior existence of libertarians, which depends on the success of the folk activism that produces them.
